Chamber bell DH21 scrubber

Divex product motif logo.jpg

The Kinergetics DH21 scrubber is one of the most widely recognised hyperbaric environmental products in the diving industry, providing an efficient means of removing carbon dioxide (CO2).

The radial flow design draws chamber or bell gas in from the outside of the canister and passes it through the sodalime “bed” where it is scrubbed of CO2 before entering the gas flow chamber and exiting back into the atmosphere.

  • Manufactured from stainless steel, the DH21 has a robust design, with excellent resistance to corrosion.
  • It operates at a lower cost and uses less power than previous scrubber and heater designs. The air mover can be used for either heater or scrubber.
  • Less spares are required as compared to older style models with more parts and a more complicated assembly.
  • The unit is smaller than previous scrubber and heater designs and there are vibration eliminators which are used in mounting for quiet operation.
  • Micro cut-out switch eliminates electrical overload in event of fan being interfered with. Can be reset by switching on/off power supply.
  • It will operate on 24 volt AC/DC 0.8 amp at surface,1.2 amp at depth.
  • Comes fitted with EO connector.
  • The mounting is the same as the DH12, directly interchangeable.
  • The Kinergetics heater or scrubber is provided with a 12 month/3,000 hours standard warranty.
